雙糙面土工膜：天高雙糙面土工膜是以聚乙烯樹脂（PE）為原料，添加納米級碳黑和其他添加劑制造而成。與現有防滲材料相比，天高土工膜具有優異的抗老化性、抗紫外線性、抗氧化性、抗化學腐蝕性和抗生物酶降解性。

雙(shuang)糙(cao)面土工(gong)(gong)(gong)膜(mo)表面由(you)不規(gui)則凹凸狀結構組成，摩擦系數高，一般應用在(zai)陡(dou)坡或邊坡膜(mo)體表面需要(yao)覆(fu)土等要(yao)求有較大摩擦系數的工(gong)(gong)(gong)程(cheng)(cheng)項目(mu)中(zhong)，是山(shan)區施工(gong)(gong)(gong)、陡(dou)坡施工(gong)(gong)(gong)等工(gong)(gong)(gong)程(cheng)(cheng)項目(mu)的首選材料。天高雙(shuang)糙(cao)面土工(gong)(gong)(gong)膜(mo)帶光滑邊緣在(zai)進行無(wu)縫焊接時，顯(xian)示了優良的性能。
